Action strength
      #175390 - 12/02/11 11:01 AM

I have ended up with a E grade Le fever 12 GA with Damascus barrels. That someone has ruined by chopping them off.Any opinion as to if this action would be strong enough for a low pressure round like 32.40 or ???.Just hate to throw it into the parts bin. But if necessary I will. Thanks for any advice. whitey

32.40 from memory is pretty anaemic isn't it ?

What the pressure it generates ?

Can't see it being a problem unless I have my calibres
mixed up.

Nitro thanks I think about 12.500 ? And I live way out on the eastern plains of Colorado. And can't get the google map deal to work. Maybe at 74 I am just too senile. Smile Whitey

12500, most actions would handle that I think.

Have a look back at what other Shotguns have been used
and what cartridges have been made on them.

whitey

A shotgun cartridge produces more than 12500,
that's what I was getting at.

So if it can handle that, it should handle the 32-40.

Seems to me the Lefever didn't have underbites, but some othr wierd mechanism. I'd not make anything other than a shotgun out of it, or maybe a BP small round like .32/20, not .32/40.

With underbites, it probably would work fine in .32/40, but might be pretty heavy?

This was the only one that I found .

Wasn't the 50-110 a low powered round for rifles like the Colt Lightning? Wouldn't have a problem digesting that.

The .50/110 was designed for the Model 86 Winchester, much stronger even in the black powder version, than the Colt Lightening. There was a later smokeless powder load for the .50/110, which drove a 300gr. bullet at 2,200fps, same as the later and smaller cased and smaller diameter .405 Wincheser. The .50/110 was a powderful round, just not very accurate due to the ridiculous 56" twist in the Winchesters.

Too - it and the .50/95 were the laughing stock of the plains, amongst the buffalo hunters, due to it's poor accuracy and penetration from it's light for calibre bullets. Instead of rescuing the .50/95, the .50/110 had more of the same problems. The too-slow twist may have had a part in that, as the bullets would not remain straight-on after impact due to instability, barely able to stay that way in the air. Even 48" and 56" are round ball twist rates, perfect for a 175gr. to 180gr. .490" to .500" ball, not a 300 to 350gr. slug.

The .50/95 a black powder only round, was designed for the model 76 Winchester, and may have been chambered up in the long chambered Colt Lightening - I'm not sure. I suspect the .45/75 Winchester might have been, also a Molde 76 Winchester round.

Maybe the Lefever action is just fine - I don't know, but envision a wierdly latching mechanism for some reason that doesn't seem very strong to me.

This vision of what I think I envision as a Lefevre might be way out in left field.

I am assuming you are refering to the pre-Ithica LeFevre. They are a great shotgun but not the best choice for a double rifle. You might think of using the existing mono-block and making a new set of shotgun barrels for the gun.

It is the small calibers that are the biggest bores.

Whitey,
I have a G grade Lefever here and took a quick look at it, it doesn't have any underlugs or bites. The only thing that keeps it from opening at firing is a rather hefty Dollshead extension with a locking notch cut into it across the back of it. You might just get by with it for a 32-40 but as stated previously, it will make up into a very heavy 32-40 at best. If you have to use it for conversion, I would humbly suggest making it up as a rifled shotgun. We know it will stand those pressures and it won't be as heavy when finished. You might also consider sleeving it back to a smoothbore. How long are the remianing barrels? If you have enough length left, you might consider putting chokes back in it.

I'm not sure how well the damascus barrels would thread for the use of screw-in choke tubes, but there are solder-in, fixed choke sleeves that could be added. Bob
